* The new ocaml compiler (4.00) has a lot of very cool warnings,Gravatar regisgia2012-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | especially about unused definitions, unused opens and unused rec flags. The following patch uses information gathered using these warnings to clean Coq source tree. In this patch, I focused on warnings whose fix are very unlikely to introduce bugs. (a) "unused rec flags". They cannot change the semantics of the program but only allow the inliner to do a better job. (b) "unused type definitions". I only removed type definitions that were given to functors that do not require them. Some type definitions were used as documentation to obtain better error messages, but were not ascribed to any definition. I superficially mentioned them in one arbitrary chosen definition to remove the warning. This is unaesthetic but I did not find a better way. (c) "unused for loop index". The following idiom of imperative programming is used at several places: "for i = 1 to n do that_side_effect () done". I replaced "i" with "_i" to remove the warning... but, there is a combinator named "Util.repeat" that would only cost us a function call while improving readibility. Should'nt we use it? git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15797 85f007b7-540e-0410-9357-904b9bb8a0f7

* Fix Extraction Implicit on axioms.Gravatar aspiwack2012-08-24
| | | | | | | There was a small bug causing the type in OCaml commentary not to honor the implicit declaration, whereas the rest of the code did. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15764 85f007b7-540e-0410-9357-904b9bb8a0f7
* Experimental support for a comment in the files' preamble in extraction.Gravatar aspiwack2012-08-24
| | | | | | | | | | | | | | | Scheme comments are output on a single line because Ocaml's Format module which serves as a backend to Pp has an integer, rather than a string as identation value, so we cannot make it so that each new line in the comment starts with ";; ". I've tried something with Pp.ifb but it was hackish at best and had somewhat strange results. Known bug: as Pp.std_ppcmds is non-persistent, the comment is actually printed only once per Extraction command, even if it outputs several files. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15763 85f007b7-540e-0410-9357-904b9bb8a0f7
* Add option Set/Unset Extraction Conservative Types.Gravatar aspiwack2012-08-24
| | | | | | | | | | | | | | | | | Extracted code need not preserve typing relations (e:t) from the source code. This may be a problem as the extracted code may not implement the intented interface. This option disables the optimisations which would prevent an extracted term's type to be its extracted source term's type. At this point the only such optimization is (I think) removing some dummy λ-abstractions in constant definitions. Extraction Implicit is still honored in this mode, and it's mostly necessary to produce reasonable types. So in the conservative type mode, which abstractions can be removed and which can'tt is entirely under the user's control. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15762 85f007b7-540e-0410-9357-904b9bb8a0f7

NB: to_int may raise a Failure if the number is larger than max_int. * In numbers_syntax, computing the height of bigN trees via bigint is *really* overkill, int should be enough there : this limits printable/parsable bigN to (2^31)^(2^max_int) ... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15669 85f007b7-540e-0410-9357-904b9bb8a0f7

* Internalization of pattern is done in two phases.Gravatar pboutill2012-06-14
| | | | | | | | | | | | | | | | | | First Notations, syntactic definitions, primitive entries are tackled to build raw_cases_pattern_expr. Reference are revolved at this time too. Then raw_patterns are internalized as cases_pattern or applied inductive (dealing with implicit args, or_pattern refactoring, aliases). It is more uniform, it allows notations for non fully applied constructors but : - It does not raise a warning when an identifier is also a global_reference different than a constructor. - It looks for implicit arguments twice. (because finding scopes of arguments asks for implicit arguments). - It does not deal anymore with constants that evaluates to constructor. (This one is voluntary, dealing with implicit & notations is already a hell full of bugs so what will be next step ? Any terms that computes to a pattern ???) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15439 85f007b7-540e-0410-9357-904b9bb8a0f7

* Corrects a (very) longstanding bug of tactics. As is were, tactic expectingGravatar aspiwack2012-04-18
| | | | | | | | | | | | | | | | constr as argument (rather than openconstr) assumed that the evar_map output by pretyping was irrelevant as the final constr didn't have any evars. However, if said constr was defined using pre-existing evars from the context, the evars may be instantiated by pretyping, hence dropping the output evar_map led to inconsistent proof terms.
